We look at the division of 439539 by 16 
The aim is to understand the frequency of 16 in 439539.

Advancing to step 1:
4 divided by 16 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 16

Step 2:
If we divide 43 by 16, we get 2 and a remainder of 11.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 32 from 43 to get 11.
Take the next digit (9) from the dividend and append it to 11, then repeat: 119 / 16

Advancing to step 3:
When dividing 119 by 16, we get 7 with a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 27.0
Subtracting 112 from 119 leaves us with 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 16

Going ahead to step 4:
When dividing 75 by 16, we get 4 with a remainder of 11.
Record the quotient 4 as the next digit in the result. 
Result so far: 274.0
Subtracting 64 from 75 leaves us with 11.
Bring next digit (3) of the dividend behind the 11 and repeat the process: 113 / 16

Let's proceed to step 5:
16 can be fit into 113 7 times, resulting in a remainder of 1.
The next digit of our result is 7. 
Result so far: 2747.0
Subtracting 112 from 113 leaves us with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 16

Step 6:
The number 16 fits into 19 1 times, leaving a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 27471.0
The remainder is 3 after subtracting 16 from 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
When dividing 30 by 16, we get 1 with a remainder of 14.
The next digit of our result is 1. 
Result so far: 27471.1
Deduct 16 from 30 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 8:
The number 16 fits into 140 8 times, leaving a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 27471.18
If we subtract 128 from 140, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 9:
16 goes into 120 7 times with a remainder of 8.
The number 7 becomes the next digit in our result. 
Result so far: 27471.187
If we take 112 away from 120, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 10:
16 can be fit into 80 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 27471.1875
Subtracting 80 from 80 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 11:
When dividing 0 by 16, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 27471.1875
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 12:
When dividing 0 by 16, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 27471.1875
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 27471.1875 with a remaining 0.0.
